mechanism connected up in circuit with the same.

The object is to provide an apparatus of this character which has the capacity to record numbers of unlimited capacity, and it is specially designed for use as an employees recording device, which has means for receiving and recording the number of a watchmans signal station or stations, and will print the year, month, day, hour, minute, as also record the forenoon as well as the afternoon of the day, and in the cases of locks will also pri;:.:.t the in or out signal and register the key used in looking or unlocking any door in the system, as well as note on the printed slip the position of the in or out at the employees entrance plate.

A further object is to provide a recorder which is electrically operated and also prints the operations of a plurality of numbering coils and timing devices of different apparatus used for diverse purposes, the signaling stations of which may .be located at distant points, and to so arrange the mechanism that the difi'erent signals, although given at substantially the same. time will nevertheless by a selective system be taken up and recorded.

It still further provides a recorder with electrical. coils to register numbers, letters,

figures and characters, words, like In and Out or other words, such as classified or secret codes, to have rolls to advance a printing ribbon, rolls'to advance a paper web, a hammer to print, and a manually-wound spring motor for the same, all of which will now be set forth indetail; I

In constructing our invention we provide a frame made up of a pair of vertical walls 10 11 to receive between them the printing and recording mechanism, held in 'alinement by suitable cross bars 12, and-on the front side is a casing, comprising a front wall 13, and secured by frame-holding pins 14:, to receive within it the motor spring and mechanism' connected therewith. In case we should use an electric 1 means for doing the print- .ing this casin need not be used. On the rear side is a. circularly-formed extension to hold the type bars and printing mechanism connected therewith. VVhiIe, therefore, the wall 10 completely separates the mechanism of the main frame from the spring motor mechanism in front of the wall 10, we have eliminated the wall 10 in" the drawing, Fig. 1, for convenience in illustrating and pointing out the connections of the various parts.

Centrally within the motor case is a shaft 14 on which is loosely mounted a drum 15 spring 18, the other end of the Patented Dec. 15, 1914.

. view of a portion of the frame showing deto receive and hold one end of a coiled drive spring being secured to the peripheral wall of the drum.

A ratchet wheel19 is fixed to the shaft 14' I and a pawl 20 hinged to the side wall 10,

the ratchet'wheel. The shaft or arbor 14' extends thi'ough the wall lO of the case, as

and has a coacting spring 21, engaged with at 22, so as to provide means for winding up the spring in the usual manner.

At the upper end ofthe frame and to the right of the spring motor driver is a shaft 23 on which is hung an escapement24, the

lower end of which has within two contact surfaces 25, 26, opposite eachother and 011 a horizontallinejwith a 'cam shaft 27, parallel with the'hanger shaft 23.. This shaft has a wheel 28 provided with four A-shaped cam faces 29, the angles of the A-shaped cams corresponding with the angles of the contact faces 25, 26, of the escapenient. The contact faces are opposite to each other inrelation to the A-shaped' cam faces 29, for purposes which will be explained hereinafter. A pinion 30 mounted on .the shaft 27 is in engagement with the main driving gear 16.

The lower end of the escapement has a notch 31 so as to provide stop walls, and thus limit the oscillating-movement of the escapement. Below this notch of the escapement, is a rock-shaft 31, which has fixed thereto a rectangularly-formed body 32, in the upper side of which are two vertically-disposed pins 33 projecting out a 'sufiicient distance to normally rest within the notch 31, and spaced apart in such a manner that when one of the pins rests against its corresponding wall the other pin will be slightly beyond the other 'wall of the notch, as shown in Figs. 1 and 5. These pins are capable of a slight in and outmovement, being normally held up against the escape- .ment by means of springs .34.

. An arm 35, which passes through the rocksliaft 31, extends out a short distance Where it is hinged to a vertical transmitting bar 36,-'Fig's. 1 and 5, that extends down and has its lower end. pivotally attached to a horizontal bar 37 the opposite end of which is hinged to a post 38:

The type bar magnet 39 has in close proximity to it a post 40, to which is hinged a horizontal lever 41, provided with an armature 42 directly above the magnet 39, and a spring 41 secured to the post 40, and having its free end beneath the bar 41, which serves to keep the armature normally away from the magnet 39. This lever 41, which is thus thearmature bar, is

' for the purpose of operating the type bars,

' end of which is hinged to the armature one of which'isshown atr42", Fig. 5. This type bar is hinged at 43, and has a type 44 at its free end, and its other end 45 is bent and hinged to a vertical link '46, the lower bar 41.

The horizontal bar 37 which transmits motion from the escapement and the armaqture bar 41 are connected up by means of a vertical link 47, "the upper end 'of which passes through the bar 37, and is adjustable by a lock nut 48, and its lower end is hooked the upper end of to a common escapement bar49 hinged to posts 50, and a bar 51 extending along below all the armature bars, of which 41' represents only one in the ser1es,-so that the.

action of the magnet in drawing down the armature bar 41 will be to transmit aidownk ward motion to the'bar 37 and common escapement bar 49, and thus rock the shaft 31. The escapenient lock-pin holder 32' being thereby oscillated or tilted, one of the pins 33 will be released from the end of the wall of the notch, and as the cam wheel is turned by the main drive gear counter clock wise, the inclined coacting surfaces between the contact 25 of the escapem'entand A-shaped cam 29, will throw the escapement to the left until it is caught by the other pin 33 At the same time thatthe armaturebar 41" moves downwardly the type bar 42" is also swung upwardly to print the character thereon.

As the 'main gear 16 is designed to actuate the paper feeding mechanism, and as the paper must be moved forwardly only a limited distance at each impulse of the magnet, or during each baclc and forth swing of the escapement, We have provided a reducing gearing which affords a simple step movement.

It should be observed thatthere is an armature bar 41 and a coil 39 for each of the units digits, andthat theaction of the of the springmotor I units digit .aswell as actuate the escapenient 24' through the underlying common escapement bar 51. Each of the tens digits has also an'armature bar andmagnet similarly constructed, but each digit is printed by itscorresponding typebar without alfecting the escapement 24 since the tensdi'gits have'no bar similar to 51. r The paper web rollers. 53, 54, are mounted on shafts 55, 56, journaled in theside walls 10, 11. The shaft 55 projects through the wall 10 and carries thereon loosely a small pinion 57 which meshes with the main drive gear 16, and is also connected with a larger intermediate idler gear 58 on the same shaft.

A Maltese cross gear59 is secured to the shaft-55 close to the wall 10, which engages with the concentric open flange 60 on the side-of the wheel 61, this latter wheel being mounted on a shaft 62, and has on one side,

close to the 'Maltese gear 59, a pro ecti ng stud 62', this stud being slightly beyond the separated ends '63 of the flange 62, and

adapted to engage with the radial slots. 64 i of the Maltese gear 59. In action one of the incurved faces 65 of the Maltese gear, which are the same are as the-concentric flange 60, rests against the flange and thus prevent the Maltese gearandthe paper feed rollers 53 I from turning,'but"whenthe stud 62 engages with one of thera'dial slots 64 one of the points 'oftheMaltese gearfenters the space between the stud and'end of the concentric flange,"as at 63', thus impafting a rotary movement to the Maltese gear and feed roller a sufficient distance to move the paper forward one space.' The intermediate idler-gear58 also engageswith a small pinion 66 mounted on the outer end of a short ed on: the rear ends of links 82, the forward .e'nds of'which. are hinged to a. bracket 83 shaft 67, and to the inner end of the shaft is fixed a'large-pini0n58 engaging with pinion 69 on the end'ofa' shaftg'ZO which CHI-1 ries the roller 710f the printing ribbon 72.

:A similar pinion'73' is mounted on a shaft 7 1, which carries the lowerribbonroller 75. Anintermediate gear 7 6 communicates motion from the gear 69 to gear At the 1 other end of the case is a pair of rollers '77 78-mounted to correspond with the posi- Y tions ofthe rollers 71 7 5, around which the with -a spring 80 resting against the belt'to' place a drag on the wheels '7 7 and 7 8 so-th at theltop limb of the ribbonfl72, passingftdward the right, will be'taut.

The upperpap'er feed roller 54. is mount on the hammer frame 84 to the wall 10. The. hammer frame 84 has "a hammer "ertically-movable within guides the frame.

This hammer bar' 85has a, yoke 86' adapted. to receive within it a four-pointed cam 87"- mounted on a shaft 88, and this shaft ex- "tends past the main drive gear 16"an'd carries'there'o'n 'a' smalljfpinion' 89 by means of "which'the cam is actuated." lVithin' the naryltime Clerk 65.

shown by the detached Fig. '6.

.The printing wheels are mounted on a fixed shaft 100, on a line with the hammer pad 9%,and this shaft has thereon'printingrollers or wheels adapted to print themonth, 101,"d'ay, 102-,- hour 103, minute 104:, a. m. and p. m. 105, year 106, and a special wheel 106 which may be used as a late designating wheel, or it may be used forany' other purpose. "It: is obvious thatthis'seii'es of wheels may be extended for other purposes not enumerated-herein, to print other characters. Directly on a line'with the pad and beyond the printing wheels described,-

is a pivoted "segment 108, havingon itsperimeter the designations In ands Out 107 operated as 'Wlll be" hereinafter de-- scribed, and a space 107 to receive the impressions from the type printing bars 42.

The in and out segment 107 Fig.1 is hinged on a fixed stud 108 so, that when it is oscillated'backand-forth it Will bring the words-directly below the printing pad,

and on a line with the printed characters ofthe pritning wheels. I spring 109 bearing against the 'segmentf'seiwes to normally throw the-segmeritcitefr. co -indicate in. The segment is connected link with an armature 111 of the magnetjl'12. Thearmaturelll is hingedat its lower end -.to the magnet frame and has a member which extends below the hinged pointwhi'ch is bent at approximately right angles .and'engages a spring 113 to normally keep it from engaging with the magnet.

A lever .114: "mountedjin apost 115 on the frame 116 of the "magnet, has a dog-catch 117 in engagement with the free end of the armature 111,-a'nd when so engaged the armature" is in contact with the magnet 112. The other end of the lever 11 i has an armature- 118 directlyab'ove the vertical magnet 119. A spring120, fixed to the post 115, and in contact with'the'dog-catch end of the lever 11a serves to keep thelever in engagement with the armature -112, unless the coil 119.is energized. 1

It will thus be seen that the segment 108', being connected with the armature 111, and normally held so that'the type ln is in position-for printing, represents the condi tion in which the apparatu's'is set for the working-shift,that is during the periods from S to 12 andfrom 1- to 5. I We also place in the'saln'e train of printing wheels-on the fixed shaft 100, Fig. 2, a-wheel'106, which hasthe word Late as hereinbefore pointed out, which wheel is actuated by a magnet 12? connected up in circuit with .a cloclr ior having mechanism ofsuch a character as to in the copending application .of Alfred L. 4

Sohm, Serial No. 581,793, filed September In order to'more fully show the operation of the recording instrument we illustrate diagrammatically the circuiting of the system in Fig. 11, in which we show a diiferential-non-difierential magnet 128, the end:

' other side of the buttons of the units digits have conductors 139, each of which connects with one terminal of the magnets 39, the other terminals of the magnets being connected up by a common conductor 140-with one terminal'of one positive winding 129, and the other terminal of this winding connects up with one pole of the battery 132 through wire 141. The conductor 140 also has a wire connection. 142 with one terminal .ofthe In controlling magnet 119,- and wires 143, 144 from the other terminal of the magnet to the ..-In button of the en-. trance plate 133. The tens column a conductor 145 which connects with one terminal of the typeprinting magnets 39', and from each magnet is a; connection to a common. conductor 146, whieh connects with one terminal of the non-differential winding 129 of the magnet, the 'otheFterminal being connected bywire 147 with the battery 132. The common conductor 146 is also con nected with one terminal of the Out controlling magnet 112, and this magnet is connected up with the Out push button 148, at the entrance plate, through wires 149,150.

-The watchmans plate, designated by 151, has :1 digits column which, in practice, has

' circuit closers or plugs, and the sockets for has, awire 157 .connectedup with one termi-- these plugs are connected up with suitable wires 152 with the tens side of the entrance plate 133, through wires 145, and 1)}? Wires 153' with wires 139 which connect with the units digits column at the entrance plate.

A mistake button 154 has one side connected with the common conductor 1.36, the

other side havinga wire 155 which connects with one terminal of an operating magnet 156, and the other terminal of this magnet nal of the non-difierential winding 12 9.

The electrical clock referred ,to-is con of-fidigits 13 5 have each is not described herein.

nected .up in circuit with the battery through the wires 97, 98, and the electrical alarm and lock mechanism are connected up by means of a wire-150 which goes to the Out button of the entrance plate, wire 159, which connects with the In button of the entrance plate, and wire 160 which connects with one terminal of the difl'erentialwinding 131.

The 0 eration of the machine is as follows s the instrument is designed to record the impulses from a variety of mechanisms, such as terminals for employees entranceplates, clock alarm,'and watchmans circuits, and for locks, or other similar apparatus which it is desired to have connected up in a circuit and recorded at a central station, and to thatend the recorder is provided with a plurality of recording wheels all mounted on the fixed shaft 100 or located in such a manner below the hammer that the characters'will be printed on the paper web 96, andthis paper is when printed, adaptedto be torn ofi'= where itemerges from the casing at 125, Fig. 1, and the slip will thus have recorded thereon, in successive order, the Various impulses from the different instruments in the circuit, in:

the order of their time, giving the year, month, day, hour and m1nute, whether a. 'm. orp. m. and also an In and an Out designation, as well as a character, for instance.

for a watchman, and also the record of locks, with the numbers and whether locked or unlocked, with the dates.

Asthis' application has nothin to do with the structure of the clock which electrically operates the type printing wheels, it

The recording instrument being in the stance, at the employees entrance, for registering the time of employees, the employee on entering will note the visual plate onthe entrance. plate. If the visual shows In, and assuming his number to be 73, he will press the button 7 which is in the tens .col-;

umn of the plate, andthen 3 of the units column. I

The resultant action of the recorder'is as follows :'When* the signal 7 .is sent the office and the transmitting button, for intens coil of the recorder is energized, there- 5 by drawing down the character ban-41. Asi'j' the tens coil 39' is connected only with the v type bar 42, through the link 46, the figure 7 will be printed on the recorder slip and there is no further operation. The employee then presses button 3 of the units column and energizes coil 39 of the units set in the -recorder,-and as the armature bar 41 :in this case is connected ,with both the'type hair 42 through the link 46 and also with the es- ,capement 24 through the bar 51, link 47, bar

37, link 36, and-oscillating stop member 32,

the section releasesfthepin 33 from the coiintenclockwise b the main driving-gear IGtu'rnsa quarter 7 eiolution, throwing the escz'i'pementto the right and is arrested by one of the teeth 2 at the inclined face 26."

Thus an impulse is transmitted f-rom the main gear 16 to the intermediate gear 57 and flanged-ii'heeltl, through the Maltese gear 59 to the paperroll shaft 55, which nroves the )aper web forwardthe requisite distance. he cam-wheel receives "its first i111pulse-by the downward movement of the link '36 and when the actuating coil is deenergized'the stop-member is again brought back to its original position so as again to swingthe'escapement to the left in'the position shown in Fig. 1. During this opera ti pn the ribbon-rolls 69, 73, are also actuated through the intermediate gears 66, 68. The cam 87 of the hammer 85, being also geared up with the main drive gear 16, and the hammer being normally held up by the bar 90 which rests on one tooth of the cam. the action of the escapement turns the cam and the spring 92 drives down the hammer which is again restored by the nexttooth of the cam. I r

It should be observed that the escapement being controlled by the pins 33Vand operated by the bar 51, every time a units coil is energized, will be actuated so as to allow the transmitting pinion 57 and also the hammer cam-pinion 89 to make one-fourth of a revolution. Neither the paper nor the ribbon can move until the hammer returns to its normal position, as the common escapement bar 51, Fig. 5', must be returned to its normal. position before the escapement will allow the stud 62, Fig. 1, to mesh with the Maltese gear, and asit requires only aboutof, an inch movement in gear 89 to allow the hammer tobe tripped, it takes of an inch movement of the stud ,62 to move the Maltese gear. As both digits 7 and 3 have been printed, the mechanism is held until the other printing mechanism, namely the hammer, stamps the'remaining portion of the line on the slip and returns to its normal position.
